The cartoon, posted by Xinhua News Service, depicts two men in business suits clinking glasses of wine and chanting 'to freedom,' while a crazed-looking man next to them finished their sentence with 'of shooting', reports Daily Mail.

The gunman is wearing a shirt adorned with a skull and surrounded by a spray of blood as he blasts off a long gun and pistol. He's standing over a gravestone that reads, 'death from firearm', reports the British newspaper.

"How a gun-happy nation spends its #FourthofJuly weekend," read the caption.

Republican lawmakers slammed China over the issue.

In a Tuesday email to Fox News, House Foreign Affairs Committee ranking member Michael McCaul, R-Texas, eviscerated the post as showing everyone "just how crass and violent the Chinese Communist Party is that they have their propaganda outlets celebrating the deaths of 450 Americans over the July 4th holiday."

"The CCP is currently committing genocide against ethnic and religious minorities in their country and are brutally cracking down on peaceful protesters in Hong Kong who are simply crying out for freedom," McCaul said.

"Until they stop murdering and imprisoning their own people, I don’t believe anyone in the world should look to them for moral advice," he added.
